ABSTRACT:
An apparatus for straightening a cylinder head of an internal combustion engine is provided. The apparatus includes a pair of elongate members on which the cylinder head is mounted. Tensionable members are adjustably anchored in the elongate members and pass through bores in the cylinder head. Tensioning means provided on each tensionable member enable desired forces to be selectively applied to the head to provide corrective deformation of the head. The apparatus is versatile and accommodates cylinder heads of most known makes of internal combustion engines.
